Funny i've been looking at this on my RB25 over the weekend, i'm trying to delete that entire unit but also trying to keep that valve somewhere in the oil circuit.

The ball's are there to allow engine oil (unfiltered) to get into the engine when the oil filter is either so blocked and doesn't allow oil to flow any more because it hasn't been changed for so long or if the anti drain back valve doesn't open completely blocking flow to the filter.

Its a fail safe device, if the filter fails, the engine still gets some, but limited oil.

If one of your balls is missing, it means your engine is getting some unfiltered oil flowing through to it.

      @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.

      I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.

      Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
